@mengxr From those docs: "StringTokenizer is a legacy class that is
retained for compatibility reasons although its use is discouraged in new
code." `Splitter` is not (only) regex-based:
http://grepcode.com/file/repo1.maven.org/maven2/com.google.guava/guava/14.0.1/com/google/common/base/Splitter.java
It's good for matching a handful of characters directly. Minor point for
sure, just seems funny to write manual parsing code. If it's
performance-critical I could see needing to hand-tune it but is it?
